God expects us to be great thinkers. The Bible wasn't written to instruct us on exactly every step we need to follow in order to obey him. When he tells us that we need to love our spouse, He didn't tell us every specific way to demonstrate that love. The same is true with our responsibilities in parenting, studying, growing, avoiding sin, doing good to others and spreading the gospel. God has called us to do things we've never done and in areas of where He's instructed us in general terms, we need to thoughtfully follow Him.
